It seems like my firewall has self healed the hole where the tachometer wire feeds through.
Burdar (thanks,Darren) sent me a pic of where it goes through on a Challenger but my firewall does not have a hole in the same position. And I cannot find the hole where it came from. The tach wire has been disconnected for 5 years now so my feeble memory is no help.
Thanks in advance if anyone has a picture or a description of where it goes.
